How do I set a Registry Value to 0x3???

We've been having issues with a 33 error on our servers, and called Microsoft. They gave us some Reg changes to make, and update 4 files on our server, and so far this has helped. but they also noticed some other stuff after examining the UDE.

They asked me to put in the below setting, but I'm unsure what chose to choose.

I have two(2) Intel Xeon e5345, QuadCore 2.33GHz processors. So I'm not sure if I set it to 0x3, or do I set it to 0xf

By default it was set as 0xffffffff

The second part is if I wanted to have it set to 0x3, do I set the value to 30000000 or just 3 so it shows as 0x00000003

Same for 0xf or 0xf0000000



1.Click Start, click Run, type regedit, and then click OK.
2.Expand the following registry subkey:


3.Right-click ProcessorAffinityMask, and then click Modify.
4. In the Value data box, type one of the following values, and then click OK:¿If you have two processors, use the binary value 0b11, or hex value 0x3.
¿If you have three processors, use the binary value 0b111, or hex value 0x7.
¿If you have four processors, use the binary value 0b1111, or hex value 0xF.

5.Quit Registry Editor.

it should be just a decimal value of 3.


Just use the decimal option in regedit.
